2014 Open House on North I-25 Improvements

A public open house was held on October 8, 2014, to provide information about planned additional lanes on I-25 and other transportation issues including interim improvements planned for early construction, commuter rail updates, and planned 2015 express bus service.

2011 North I-25 EIS Record of Decision

The Federal Highway Administration (FHWA), in cooperation with the Colorado Department of Transportation (CDOT), prepared a Final Environmental Impact Statement (EIS) to identify and evaluate multi-modal transportation improvements along the I-25 transportation corridor extending from the Fort Collins/Wellington area to Denver.

The Final EIS was released for public review in August 2011, and corridor-wide public hearings were held during September 2011 to collect public input during a 45-day comment period.

In December 2011, FHWA signed the North I-25 Record of Decision (ROD), the federal document that describes the transportation project, explains the rationale for the project decision, responds to public comments received during the Final EIS comment period and makes commitments as to how the project will mitigate impacted environmental resources. The signing of the ROD completed the National Environmental Policy Act (NEPA) process for the North I-25 EIS. The completion of the NEPA process better positions the North I-25 improvements to qualify for state and federal funding.
